EVA/TPU interlayer glass is a core material in building curtain walls, automotive windows, photovoltaic modules, and other applications. Its quality directly affects the safety, durability, and user experience of the final product. To ensure that every roll of interlayer material can withstand market scrutiny, we have established a professional laboratory to conduct comprehensive performance tests using scientific methods. We use precise data to build a solid quality defense line, providing reliable product assurance to our global customers.

Light transmittance is a core optical indicator of membrane materials, directly affecting lighting effects and visual experience. We use professional optical testing instruments to accurately measure the membrane materials under standard light source conditions, ensuring that the product's light transmittance consistently reaches over 90%, maximizing the restoration of the transparent texture of glass and meeting the high-definition viewing requirements of high-end buildings, automobiles, and other scenarios. Simultaneously, we conduct fogging tests under simulated high-temperature and high-humidity extreme usage environments, strictly controlling the fogging value of the membrane material to ensure it maintains a low fogging state throughout long-term use, preventing fogging from affecting visual clarity and guaranteeing the safety and aesthetics of the application scenarios.

                                   

To address the complex outdoor environments that membrane materials may face, we conduct rigorous damp heat aging tests. Membrane samples are placed in a constant temperature and humidity chamber at 85℃ and 85% humidity for 1000 hours of continuous aging, simulating long-term use under tropical climate and high humidity conditions. After the test, professional equipment is used to test the membrane material's adhesive strength and tensile property change rate, ensuring that the product maintains stable physical properties even in extreme environments, without issues such as delamination, embrittlement, or cracking, perfectly adapting to applications such as photovoltaic modules and outdoor buildings that are exposed to the natural environment for extended periods.

As a key protective material in glass interlayers, the mechanical properties of the membrane material directly determine the impact and tear resistance of the end product. We use a professional tensile testing machine to rigorously test the tensile strength and elongation at break of the membrane material to ensure that the product possesses excellent flexibility and tensile strength, effectively absorbing energy when subjected to external impact and preventing glass shattering and fragmentation. Simultaneously, we conduct specialized adhesion strength tests to simulate real-world scenarios after glass breakage, verifying whether the membrane material can firmly adhere to glass fragments, preventing secondary injuries and comprehensively ensuring safety in applications such as buildings and automobiles.

From precise laboratory testing to end-to-end quality control on the production line, every roll of EVA/TPU glass interlayer undergoes multiple rigorous tests. We always let the data speak for itself, using scientific testing to verify product strength, and continuously provide membrane material solutions that combine optical advantages, durability, and safety for industries such as construction, automotive, and photovoltaics, helping global customers achieve higher-quality development.
